3.2. Pump Mounting Install pump on a level concrete slab or other rigid base to meet all local and national codes. Secure pump to base with screws or bolts to further reduce vibration and stress on pipe or hose joints. The base must be level, rigid, and vibration free. Pump mount must: • Allow pump inlet height to be as close to water level as possible. • Allow use of short, direct suction pipe (to reduce friction losses). • Allow for valves in suction and discharge piping.

To Wire a Dual-Voltage Motor Dual voltage motors have a plug to change from 230 volts (factory setting) to 115 volts. 1. Turn off power. 2. Remove the motor end cover. 3. If you have 230 volts motor supply voltage, confirm that the plug is set for 230 volts. The arrow on the plug will point to the 230 volt position. Note that plug only connects with one prong in this position. See Fig 3.9.1 4. If you have 115 volt supply, pull the plug straight up & place it on the two brass prongs as shown. See Fig 3.9.

WARNING – If circulation equipment must remain in the plumbing system during water pressure test, do not apply more than 10 psi pressure to the system. Be sure water pressure has been released, using the filter manual air relief valve, before removing pump strainer cover. WARNING –Separation Hazard All suction and discharge valves MUST be OPEN, as well as filter air relief valve (if available) on filter, when starting the circulating pump system. Failure to do so could result in severe personal injury. 4.2.

CAUTION – Use ONLY propylene glycol as antifreeze in your pool/spa system. Propylene glycol is nontoxic and will not damage plastic system components; other anti-freezes are highly toxic and may damage plastic components in the system. Drain all water from pump and piping when expecting freezing temperatures or when storing pump for a long time (see instructions below). Gravity drain system as far as possible. Keep motor dry and covered during storage.
